As the SSPX was making its branding transformation back in 2012-2013, there were several threads noting various changes to the appearance and content of SSPX websites (which seemed to be following suit with the then-announced new editorial policy of The Angelus, which we were told would no longer be so adversarial and combative).
For whatever reason, this memory occurred to me just now, so I went to SSPX.org to discover what I might find there 8-9 years later.
Not surprisingly, if you go to SSPX.org right now, there is absolutely nothing on the first/homepage indicating that the SSPX opposes Vatican II, or that there is a doctrinal crisis in the Church stemming from that council, nor that Lefebvre founded the SSPX to carry on the traditional priesthood "and all that pertains to it" (which would include the fight against Roman modernism).
Most will have forgotten about this transformation in SSPX website content, but if you compare the current SSPX.org to the old SSPX.org website (which was 90% articles opposing the various manifestations of modernism in the conciliar church), the contrast is striking.
